Abstract

A method for connecting two or more components including overlapping surface sections via a laser beam. In the method, prior to the laser welding, the components are fixed in a positive fit to at least one of the overlapping surface sections by local cold joining, preferably via rivets or screws and are then laser welded, a laser weld seam being created in close proximity to each fixing point that has been produced by cold joining, in particular as close as possible to the rivet or screw.
